According to this article, analyses of in situ station data and satellite observations of precipitation have identified another problematic trend: main growing-season rainfall receipts have diminished by 15% in food-insecure countries clustered along the western rim of the Indian Ocean. Occurring during the main growing seasons in poor countries that depend on rain-fed agriculture, these declines are societally dangerous. The article quantifies the potential impacts of the observed precipitation and agricultural capacity trends by modelling "millions of undernourished people" as a function of rainfall, population, cultivated area, seed, and fertilizer use.
